Furnace Making Loud noises? | Milwaukee Furnace Repair
Have you noticed a noise coming from your furnace? Your Furnace can make a range of sounds depending on whether they are oil, gas or electric and depending on the manufacturer.
Most annoying sounds are harmless and easily fixed. Other sounds suggest
serious problems, some of which can cause dangerous carbon monoxide to
leak into your house.If your furnace starts with a loud "whomp or Bang," the air to fuel mixture is likely wrong or
your ignition is delayed. If your furnace hums or roars loudly when it
starts, the inducer motor is probably bad. If your gas furnace clicks
when you start it, the flame condenser might be dirty. If your furnace
howls loudly when it kicks on, your heat exchanger might be cracked. You
should get that fixed immediately because it can leak dangerous carbon
monoxide.
When you hear a loud sound like an explosion when you turn
on your oil furnace, you likely have a weak transformer, a clogged
nozzle or you need to reset the electrodes. If your furnace roars, your
burner might be dirty. A dirty burner will not light correctly and when
it does light, the gas makes a torch sound as it shoots back to the
hole where the gas mixes with air. If the pilot light of your natural
gas furnace gets hit by the draft of air from the roof vent, it can
flare up, making a roaring sound.
If your furnace rumbles, unburned oil from a dripping or
dirty nozzle may be collecting on the floor. When the furnace shuts off,
the oil on the floor continues burning, making the rumbling sound. You
need to get this fixed because it can cause a build-up of carbon
monoxide. If the blower of your furnace makes a low, loud sound like a train, its bearings are probably bad, and you may have to replace it.
If your furnace rattles or bangs loudly for about 30 seconds
before the blower kicks in, your heat exchanger may have developed a
crack. A cracked heat exchanger can cause carbon monoxide to enter your
ductwork, and you should get it fixed immediately. Children's toys and
other small objects can make their way into the recirculation system and
get sucked into the fan box where they bounce and rattle around.
If the blower on your furnace moans and groans, its bearings could be shot. If your oil furnace whines loudly, you may have bad
bearings in your draft inducer motor, which will eventually lock up and
have to be replaced. If your electric forced air furnace hums loudly,
something might be loose and transmitting the noise through the duct-work. A bad gas valve can cause buzzing that is transmitted through
the gas line.

Wow, this is a very helpful post! I remember when my sister got afraid because we heard some exploding sounds from the furnace. After consulting with professionals, we found out that the transformer was weak and we have to replace it. It’s good that we have noticed the problem early on, ‘cause if not, we would have to replace the whole furnace. And I know that will be a bigger and costlier problem. :)

When your furnace starts making noises, we are always cautious about what’s broken and how we're going to fix it. In the first place, it is important that we constantly maintain the furnace to keep it from breaking. We have to make sure that it is properly installed and in its proper place. When these ramblings occur, you have to seek for professional help with the repairs to avoid doing more damage.
